' f RUNNING BOARD.

Application tiled January 12, 1925. Serial rN'o.;`1,805.

, The present invention has todo with the provision, asan article of manufacture, of a unitarypractically integral, though composite, ruiming board structure `adaptedy for for application to vehicles.

In the-accompanying drawing, wherein Figure 1 is a transverse section, and Figure 2 a fragmentary longitudinal section, I have as applied to an automobile, although it is obvious the same is adapted to othervehicles,l and susceptible of changes in form and contour to suit particular conditions of use.

In ythe yembodiment illustrated, an imf proved running board structure is shown as comprising a sheet metal base member 11 having flanged inwardly turned marginal sidesflQ and ends 13, and alsofprovided median wider rib 15 of less height than the ribs 14. y.Both vthe ribs 14 Vand 15 have their i f upper' faces disposed below theho'rizontal plane of the inturnedmargins of the flanges spurs 16 to serve as an yinterlock with the tic substance, `which may be of anysuitable composition, now known and used as a tread filling for floors and the like, such, for example, as an asplialtic binder'with afiller of comminuted wood or cork; no claim being made 4herein yfor the novelty of ythe, composig tion per se.'y i

Metal `plates 18 are spotwelde'd or other-4 wise permanently secured to thebottom of 4 the base member 11, preferably bridging the recesses 1S)` beneath the ribs or elevations 14, these plates 18 serving with kthe bolts 20, to aflix the ruiming board detachably to the hanger irons 21 of an automobile or other n 45 i vehicle.

manufacture and sale as a standard fitting illustrated `an embodiment of the invention` composition.

with parallel upwardly facingribs 1li and ar 12 and 13, One or both of the trough bot# toms formed alongside the ribslt, and alsoV the upper face of the rbl are provided, by punching, with upwardly projecting tread body 17 of a hardened originally plas The height of the ribs 14 is substantially less than that of the sides and ends 12 and 13 yin order to provide spaces thereabove for a. sufficiently thick layer of tread composition, while the lesser height of the median p rib 15 affords space for av greater thickness VOf'tread composition tliereabove where the wear is excessive.y The interlocking of the' sheet metal base with the tread composition, bymeans of the spurs 16, constitutes a substantially integral structure of the metal and The longitudinally extending ribs 14 and 15 are advantageously modified adjacentl the ends of the running'board to provide a maxi- *mum thickness. of tread material at the ends manufacturers, and all ready for application to the vehicle.

, i I claim V f As an articleL of manufacture, a running board for vehicles comprising a sheet metal pan-like base containing a hardened originally plastic composition, the baserhaving longitudinally extending elevations Of less height'than the pan depth, a metal plate fixedly secured to the lower face of the pan and bridging the recess formed beneath the elevations, and bolts forfremovably attaching the plates tothe hanger brackets of the 'vehicle' with the ybolt heads accommodated within the recess above the plates.

In testimony whereof I have hereunto signed my naine.
